An infant boy was in "very critical condition" Sunday night after a two-vehicle crash on the Eisenhower Expressway in west suburban Forest Park, his family said.

The 10-month-old boy, identified by his grandmother as T.J. Hughes Jr., was among three people injured in the crash at 3:20 a.m. Sunday in the eastbound lanes of Interstate 290 near Desplaines Avenue, according to Illinois State Police.

The child sustained two broken legs, a broken arm and a skull fracture, his grandmother Latonya Polk said. The boy was in the vehicle with his aunt after visiting his grandmother's house in Maywood for a post-Thanksgiving gathering. They were headed back to T.J.'s home in Chicago when they were hit, Polk said.

A blue 2000 Hyundai Elantra driven by a 25-year-old Chicago woman was stopped in the right lane with its lights off when it was rear-ended by a silver 2001 Honda Odyssey driven by a 50-year-old Chicago man, police said.

T.J. was not correctly secured in a proper child safety seat inside the Hyundai, police said.

He was being treated at Loyola University Medical Center in Maywood, where he was on life support, police said.

The two adults were also taken to Loyola, but their conditions were not released, police said. Alcohol was believed to be a factor in the crash.
